Justification:Erythrina haerdii has a small range with an estimated extent of occurrence of 7,989 km² and area of occupancy is 70 km². It is known from seven locations and there is continuing decline in the extent and quality of the remaining habitat outside of the protected areas due to agricultural expansion. It therefore qualifies for listing as Vulnerable.

There is likely to be some decline in the lower elevation localities due to clearance of habitat for agriculture. The tree is not used for firewood, hence it is probable that some trees would be left standing.
